RFIFO Threshold Level
The size of the accessible part of RFIFO can be determined by
programming these bits. The number of valid bytes after a RPF
interrupt is given in the following table:
RFT1
0
0
1
1
The value of RFT1, 0 can be changed dynamically.
– If reception is not running or
– after the current data block has been read, but before the
CAS Synchronization Mode
command CMDR.RMC is issued (interrupt controlled data
transfer).
Synchronization is done in accordance to ITU-T G. 732
Synchronization is established when two consecutively correct
multiframe alignment pattern are found.
Internal signaling in time slots 0-31 defined via registers
RTR1...4 or TTR1...4 is disabled.
Internal signaling in time slots 0-31 defined via registers
RTR1...4 or TTR1...4 is enabled.
Continuous logical ‘1’ is output
Continuous flag sequences are output (‘01111110’ bit patterns)
